I'm not sure what's available with Carrara's Particle Generator, but RDS's is pretty weak. I've been playing with the particle generator Litst linked to a few posts ago and it has some amazing features (although it's only 2D). Those are features I'd like to see. But I'll list what I think we should have -- 1. variable particle type (size, shape, etc) 2. variable particle velocity 3. true 3D particles (not the little 2D flakes that RDS generates 4. emitters and attractors that influence the path of each particle 5. completely adjustable particle life and duration 6. adjustable noise perameters in the particle path, life, and impulse 7. collision detect to provide appropriate bounce and deflection off other objects in the scene 8. maybe even the ability to build a small object and assign it to each of the particles in a stream (like a single model of a snowflake that becomes the particles in a stream, simulating a storm of snowflakes -- kind of like what you could do with furrific in RDS by putting an object at the end of each hair) 9. variable disbursion patterns so the particles don't have to come from one single point. Yeah, that's about it. OK, so when they develop it, I'm sure it'll bump C's price right up there with Max.... But a guy can wish.
